To be fair, guys with huge balls are more likely to be dead, and therefore absent parents. All those bare-knuckle fights they get into in abandoned parking garages and attempts to intimidate cops add up to a fatal situation pretty quick.

Me? I try to strike a happy medium. I beat up chinstrap geese down at the water retention pond.

Wait, is there another study where guys with gigantic balls are more likely to get into fights? I figured they would be more relaxed and contented with their lot.

Less nurturing isn't necessarily a bad thing, in fact, it can be good. If a man with big testes and high testosterone hooks up with a woman with a high maternal instinct then it would be a good balance.

Raising children in inflatable bubbles doesn't prepare them for the world, fathers often take on the role of "pushing them out of the nest".

It would be interesting to see the study expanded to the mothers to see their relative relationship.

The study said they found a significant difference in testes size but that just means the means were significantly different. Without knowing the variance/SD, you don't know how big the effect is. If the variance is small enough that there is little overlap between the "attentive parent" and "inattentive parent", it might have predictive value. If the variance is large, so there is a great deal of overlap between the two groups, it may be statistically significant yet have relatively weak predictive value. I imagine this data is in the paper, which I don't have access to.

Jeez, anyone not taking this seriously is getting downvoted. It's like some people are a little testes-- wait no someone already used that one. There are a pair of ballbusters stuck to the leg of these comments-- no wait that's terrible. It's like someone grazed the sensibilities of some readers and after a bit of a delay they started.. no. There once was a man from Nantucket

That's why cave girl gets knocked up by sexy exciting manly man and then marries homely boring girly man so he can help her raise kids. Meanwhile people are confused where these desires come from...</theory>
